Printable arithmetic worksheets
Choose the topics and number ranges, pick a layout, and print. Every sheet is generated fresh, so no two classes get the same questions — and the answer key is one checkbox away.
Eleven topics
Addition, subtraction, multiplication, division, decimals, squares, cubes, square roots, cube roots, percentages, and fraction–percentage conversion. Mix as many as you like on one sheet.
You set the difficulty
Each topic has its own number range. Keep addition inside 0–20 for a Grade 3 class, or push multiplication out to 12 × 12 for times-table drilling. Negative numbers are optional.
Print-ready
Grid or list layout, two to four columns, a name-and-date line if you want one, and an answer key on its own page. It prints from your browser — no download, no software.
How to get the most out of a worksheet
A generated sheet is only as useful as the range you set on it. The commonest mistake is to leave every topic on its default and print a page that is half trivial and half impossible: the learner does the easy half, stalls, and learns that maths is something that happens to other people. It is nearly always better to print a narrow sheet than a broad one.
Pick one thing per sheet
Twenty questions on a single operation, inside a single number range, will teach more than twenty questions spread across five topics. Mixing is useful later, once the individual skills are automatic, because it forces the learner to decide which method applies — but a mixed sheet given too early measures confusion rather than arithmetic.
Set the range to where they nearly cope
The useful zone is where a learner gets most questions right but has to think about some of them. If a sheet comes back with full marks in two minutes, the range was too low to be practice. If it comes back half finished, the range was too high and the time was spent being stuck rather than learning. Adjust one bound at a time and print again — it costs nothing.
Use the answer key for marking, not for teaching
Handing back a marked sheet tells a learner which ones they got wrong. Sitting with them while they redo two of the wrong ones tells them why. The key exists to make the first part quick so there is time for the second.
Why fresh questions matter
Every sheet is generated when you press print, so no two are alike. That matters more than it sounds. A worksheet that circulates unchanged becomes an answer sheet: the learner who saw it last term is not doing arithmetic, they are doing recall, and the marks stop meaning anything. Fresh questions also mean you can print the same configuration three days running and be confident that improvement is improvement.
Where this fits with the rest of the site
These sheets drill the arithmetic itself — the part that has to become automatic so that it costs nothing during a longer problem. The mental maths trainer does the same work against the clock and on screen, which suits a learner practising alone. The NBT book is where that arithmetic gets used, on the kinds of question the test actually asks. If you are preparing someone for the National Benchmark Test, the book is the spine and these are for the gaps it exposes.
A few things that work in practice
Short and frequent beats long and rare. A twenty-question sheet every morning does more for recall than a hundred-question sheet on a Friday. The default of 30 questions is about five minutes' work for a fluent learner.
Narrow the range before you widen it. If a class is shaky on multiplication, set the range to 2–5 and let them succeed, then extend upward. A sheet that is uniformly too hard teaches avoidance rather than arithmetic.
Print the key separately. Generating the answer key on its own page lets learners mark each other's work, which is faster for you and better for them — marking someone else's arithmetic is its own kind of practice.
Mix topics only once each is solid. Single-topic sheets build the skill; mixed sheets test whether it survives having to choose an operation. Both are useful, in that order.
These sheets are free to use and photocopy in any classroom, at any school, without asking. See the licence for the details.
